In a Christmas surprise, Microsoft have just unveiled the release candidate of XP SP3.
This may come as a surprise to many considering everyone thought that Microsoft were now concentrating on Vista instead and would only be releasing security patches and hotfixes for XP. It just shows how big the XP userbase is and how few have migrated to Vista so far.
The release candidate is available for everyone, but weighs in at about 336MB, and is available from the XP download centre, here. Although the final version that will be available next year (in the spring) through Windows Update and is rumoured to be a much smaller 70MB download.
